Medical Stimulating neurons via magnetic fields

    I ran across this article in "Newsweek-Next Frontiers" about stimulating neurons directly by firing large magnetic pulses to specific locations in the brain:

    Well, I can imagine a much more "accurate" device which can affect individual neurons or "local" populations of neurons. Surely if one could "modulate" the pulses in such a way to simulate the physiological process involved with real neural growth, then indeed I think we would be achieving what the article declared "Re-wiring the brain". Big 'if' though. We really don't even know how physiological processes give rise to mental ones, not exactly anyway. But still, I somewhat suspect this is the beginnings of something . . . wonderful. :smile:

    Sounds dangerous.

    It could well be. At high frequencies it causes seizures, which means at lower frequencies it probably works by disorganizing neuronal firing as well.

    It seems in all cases to be temporary if it works at all.

    Thanks for the ref Zoobyshoe. This is a quote:

    Yea, I know we're still in the middle-ages with this. You know what the first transistor looked like? We made improvements didnt' we. :smile:
